About the eartips

 

Sizes

The product comes with silicone eartips in four 
sizes (XS, S, M and L). At the time of purchase, 
the M size silicone eartips are attached and 
positioned in standard position. To ensure that 
you will enjoy the best sound quality, it may be 
necessary to change the size and /or position to 
what is best suited for you, and adjust the eartips 
inside your ears for a snug fit.

 

Cleaning the eartips

Remove eartips from the product and clean them 
with a diluted detergent. After cleaning, dry 
before use.

 

Replacing the eartips

Remove each old eartip, and mount the new 
eartip over the stem up to the base of the stem.

*The eartips are designed to fit tightly to the product 

so that they will not come loose unintentionally.

Warnings

 Safety precautions

For long-time storage, keep the product in a 

well-ventilated place without high 
temperatures and humidity.

Refer to ''Cleaning the eartips'' in ''About the 

eartips'' to learn how to clean the eartips. 

Follow applicable laws regarding mobile phone 
and headphone use if using the product while 
driving. 

Do not use the product in places where the 
inability to hear ambient sound presents a 
serious risk (such as at railroad crossings, train 
stations, and construction sites).

The product effectively shields external sound, 
so you may not hear sound around you clearly 
while wearing the product. Adjust the volume 
to a level where you can still hear background 
sound and monitor the area around you while 
listening to music.

Store the eartips out of the reach of small 
children.

 

Cautions

To ensure compatibility and correct usage, 
always consult the user manual of any device 
before connecting the product to it.

Audio-Technica will not be liable in any way for 
any loss of data in the unlikely event that such 
losses should occur while using the product.

On public transport systems or in other public 
places, keep the volume low so as not to 
disturb other people. 

Minimize the volume on your audio device 
before connecting the product in order to avoid 
hearing damage from sudden exposure to 
excessive volume.

When using the product in a dry environment, 
you may feel a tingling sensation in your ears. 
This is caused by static electricity accumulated 
on your body, not by product malfunction.

Do not subject the product to strong impact. 

Do not store the product under direct sunlight, 
near heating devices or in a hot, humid or dusty 
place. Do not allow the product to get wet.

Be sure to purchase the appropriate 
conversion plug adaptor when connecting 
the product to equipment with other than a 
3.5 mm (1/8”) stereo headphone jack.

Lengthening the headphone cable requires a 
separate extension cable available from your 
dealer.

1.

Lower the volume on the device you intend to use, then connect to 

the device's headphone jack.

2.

Make sure to place each eartip (LEFT/RIGHT) in the correct ear.

3.

Turn on your audio device, and adjust volume as necessary.

*Also read instruction manual of your audio device.

Get into the habit of regularly cleaning the product 
to ensure that it will last for a long time. Do not 
use alcohol, paint thinners or other solvents for 
cleaning purposes.

Use a dry cloth to clean the headphones. Do 

not allow the cloth to touch the area from the 
sound producing area because it is more 
susceptible to damage.

Use a dry cloth to clean the cable of any sweat 
or dirt. Failure to clean the cable may cause it to 
deteriorate and harden over time, resulting in 
malfunction.

Wipe the plugs on the cable with a dry cloth if 
dirty. Using the plugs without cleaning them 
can cause sound interruption or distortion.

Please see the shape of the earphone jack or refer to your smartphone's user manual. As the 
functionality of smartphones can vary by manufacturer and by model. Audio-Technica cannot 
guarantee this product will work with every smartphone. For the detailed information, please contact
